vieu7 talien on line 'l-X in prise an upper or iuel receiving member s element 9 and a loiver or fuel discharging' member or element 10 including a. hrepot 11.

. The fuel receiving member nay coniprise a chamber 12 olli-set from and in comnninication with a vertical conduit 13 which may be made integral with the chamber (sec Fig. 3). The chamber may be ol' any i: rit able configuration anc shoivn sul tially of cylindrical form and provided una a slightly tapered aperture 12 in its upper Wall to receive what may be termed a nozzle 14 at one end of an inlet pipe The nozzle 14 extends into thechamber 12 af distance sufficient to bring the outlet oritice of the nozzle into close proximity 'to 'the lower Wall 18 of the chamber.

This loiver Wall, Which is of relatively small arca, plays an important part inthe operation of the burner. As will presently be set forth` the vWall 18 constitutes wvl-iat may be termed a hot spot or restricted heated area against which the mixed 'fuel or saturated vapor discharged at high velocity from the nozzle 14, so as to produce a cracling7 elfect cansing the mixed fuel to be converted into gas. This gas then passes through an opening or chamber outlet 19 and into passage 1.3 for entrance to the lower member for' discharge from the iirepot ot the vfuel dischaigingelement `An important- 'feature of the present construction the provision of a large discharge conduit which permits the converted fuel Yto ass Vfrom the cracking chamber vtact with the hot spot until the fuel is y stantially completely converted into Without any compressive or back pressure upon the in-lou'ing vapors.

Especial note'is to be made ot -the construction o't the chamber 12 in that it is dcsigned to retain the fuel vapor or carburetted fuel Within the chamber and in consul gas.

' For example the Wall separating the chamvloer fromthe discharge conduit is made .sut `fciently` high to prevent the escape oli the heavier particles of oil and Vthus retain the same inthe lower portion of the chamber against the highly heated portion. Furthermore, the inlet nozzle is disposed very clos-e to the bottom of the `chamber thus bringing the carburetted Yfuel into direct contact vwith the heated spot. Means lo he more 'l'ullv described hereinafter are provided to main tain every portion ol" the bottom ol' the, chamber al' a high temperature .so that :inv vapor striling thc boi'oin ol' the chamber at any point will receive 4die action oi' the intense heat thereof.

The tirepot 11 :nay he a single casting or maj,- be composed oit tivo parla il and lil cormectcd in any suitable manner as. 'or example. by tap ijiolts 'ii shovvn iu Fic'. yl.

The part :2 ivhich includesy the h'epol 1I of the burner comprises a hovcl portion tlf? having a slightly tapered ,scat :.al about ih. upper inner periphery lo receive a per- Atorated nozzle-plate $51. rThey nfi'fLL/le--plafe in conjunction vvith the hovvl :15% provides what may be `ermed the iircpot or chamber to receive `@ses Ytroni vvilhiu the hollow body Q1 through passrws lz and ll (see Fig. 4;).
